New Achievement in Smart Early Warning: Zhongyun Technology Accurately Detects Coupling Failures, Ensuring Safe and Continuous Operation of Wind Turbines.

Recently, an abnormal vibration occurred in the dust removal fan of the raw-material workshop at a well-known food company. The Zhongyun Technology Intelligent Operation and Maintenance Monitoring Platform promptly detected a sudden change in vibration data, enabling timely on-site intervention and effectively preventing damage to the fan equipment and disruption of production.

I. Real-time Monitoring: A sudden increase in vibration data triggers an alert.

This dust removal fan is a critical piece of equipment for ensuring both a safe workshop environment and production safety. Starting December 1, 2025, the platform detected a sharp increase in the vertical vibration velocity of the fan’s bearing housing during operation—rapidly rising from 5 mm/s to 9 mm/s, exceeding the safety threshold. The platform immediately triggered an alarm and automatically pushed out comprehensive alarm information, including details on the alarmed equipment, its affiliated department, the alarm severity level, as well as the initial and latest alarm timestamps, providing the operations and maintenance team with clear and timely risk guidance.

II. Intelligent Diagnosis: Identifying the Root Cause of “Imbalance”

Upon receiving the platform alert, the Zhongyun Intelligent Diagnostics team immediately conducted an in-depth analysis of the vibration data. Combining this with the equipment’s rated speed, they ruled out common rotating-frequency faults such as misalignment and looseness. Given the equipment’s structural design, which features an elastic coupling, they determined that the sudden imbalance was highly likely caused by the detachment of a rotating component.

Comprehensive assessment: A component has fallen off the fan or coupling, causing an imbalance in the rotor system. The equipment is in a warning state and must be shut down for inspection.

III. Closed-loop Management: From Precise Early Warning to Rapid Remediation

1. Planned Shutdown and On-site Confirmation

The on-site equipment was shut down on the afternoon of January 4. After a careful on-site inspection, it was confirmed that one of the coupling alignment bolts had come loose.

2. Immediately fix the data validation.

The maintenance personnel immediately reinstalled and tightened the bolts. After the equipment was restarted, the platform monitoring data showed that the vertical vibration velocity of the fan bearing housing “rapidly dropped below 5 mm/s,” and the equipment’s operating condition returned to stable.

Core Value: A Model Practice in Predictive Maintenance

The successful handling of this wind turbine failure vividly demonstrates the three key values of Zhongyun Technology’s intelligent operations and maintenance platform:

1. Break the limitations of routine inspections: Replace manual, periodic inspections with 24-hour real-time monitoring to precisely detect early, hidden faults and achieve “early fault detection.”
2. Reduce operational and maintenance costs: By leveraging data-driven, precise diagnostics, avoid unnecessary disassembly and repairs, minimize component wear and tear, extend equipment lifespan, and achieve "low-cost maintenance."
3. Upgrade the management model: Adopt a closed-loop approach of “early warning—diagnosis—intervention—validation” to help enterprises shift from “reactive maintenance” to “predictive maintenance” and accelerate the digital transformation of equipment management across the industry.

Zhongyun Technology will continue to iteratively enhance its AI diagnostic algorithms and sensor technologies, providing industrial enterprises with end-to-end intelligent operation and maintenance solutions that offer “precise early warnings, efficient response, and stable assurance,” thereby helping the industry achieve digitalization in equipment management and intelligent decision-making in operations and maintenance.
